What Styles of wheels are available? 700C and 650C.  Road front and rear.  Shimano 8/9/10 and Campy 9/10.  Clincher and tubular/sew-up in CROSSWIND and FLY, and clincher in Spider.  Track rear CROSSWINDs, FLYs and Spiders.  Handcycle configurations in CROSSWIND, FLY and Spider.  CROSSWIND Clydesdales and Horse FLYs for heavier or stronger riders.  Tandem CROSSWIND in both clincher and tubular/sew-up.
What about tubular tires? We have advice on tubulars (sew-ups) which we think are a performance advantage.  Read our page: Tubular Tire Advice.
What is the rim made of? Tubular style rims are made of carbon/epoxy composite. The CROSSWIND rim mass is approximately 310 grams (700C tubular), making it the lightest high performance aero rim available.
What is the braking surface? The CROSSWIND and FLY tubular rim braking surfaces are carbon/epoxy. This surface has some properties that are different from the aluminum alloys used in most metal rims. Our formulation of carbon/epoxy composite makes a harder surface that causes greater brake pad wear rather than rim wear. Our composite radiates heat differently. In conditions of extensive and prolonged braking, such as mountainous European stage races, these heat properties reduce sew-up glue failure, but increase brake pad melt. In wet conditions, the smooth surface increases water surface tension, requiring more time to clear the rim. Once the rim is clear, wet condition brake grab is typically stronger and predictable.  We recommend Kool Stop brake pads as an inexpensive and excellent upgrade.

The CROSSWIND and FLY clincher style rims have braking surfaces made from aircraft aluminum alloy.

The Spider braking surface is machined alloy.  This provides very smooth, well modulated brake feel.

What are CROSSWIND clincher weights? The added weight for the clincher version is approximately 70 grams at the rim. Clincher tubes and tires typically add an additional 30 to 60 gram penalty. See mass chart.
How are wheels tested Tested? Our test program includes dozens of elite athletes in competition around the world, and product engineers and consulting scientists across an array of product development disciplines. Our advertised product claims reflect our investment in high precision/high accuracy bicycle scale laboratory equipment and design tools. Our aero drag numbers have been verified by no less than 8 protocols including: wind tunnel comparisons, calibration against various test objects with analytically derived fluid dynamic models, mechanical acceleration devices, product/product part "live air" road trials, and rider/product "live air" road trials. Independent parties have provided both data and test results that confirm our findings. Trade press reviews are ongoing.
Warranties? We currently offer a 30-day satisfaction guarantee on our wheels and a one year warranty against materials defects. We offer a no-fault, reduced-price replacement of wheels and wheel parts returned for any reason.
Handcycles? What handcycle wheels are available?  Almost every Nimble configuration has a handcycling equivalent.  See Handcycle
What are wheel weight limits Nimble offers a very wide range of configurations suiting riders from 80 to 280 lbs.  Evaluate your Effective Rider Weight (ERW) and check out our configurations with  rider/wheel weight limits.
Large riders? We support larger riders, see Clydesdale wheels and rider/wheel weight limitsTandem wheels are coming, we will announce them when ride tests are in.
How often does pricing change? Since 1996 we have changed our wheel prices three times.  We do not have winter sales.  We do support a small used CROSSWIND resale market for riders swapping wheels.  We also keep a waiting list for the rare cosmetic blemish wheel we will sell at a discount.  We maintain a limited gross margin and do not offer the frequent discounts found with other cycling goods sold through retail channels.  We hope riders will find our standard prices competitive, even with our orientation toward performance and quality.
Which cassettes are available? We have a range of cassettes available for sale in our Race Ready Program.  Also see cassette technical data arranged by drive type and gear range: cassette/gearing specs.
How are CROSSWIND hubs installed? How to install hubs and other CROSSWIND wheel lifecycle questions are discussed in our installation instructions.  This information also includes maintenance and care information relevant for FLY and Spider owners.
What Kind of Bearings are Used? The hub and bearing designs focus on two areas to improve bearing performance. The first is an investment in premium quality bearings from a leading global manufacturer of aerospace and automotive components. These bearings are a "deep grooved double sealed ball" design. The second is a hub fit system that captures bearings in high precision alignment, using a proprietary "axle dominant" press fit design.
